About the Symptom
A scab is a rough, dry protective crust that forms over a wound during healing. During the healing process, the tissue under the scab grows back and pushes out the scan to allow new skin to grow.
When to see a doctor
Seek professional care if you experience any of the following symptoms
Numbness / sensory disorder
Numbness of the body
Systemic rash
Fever
Possible Causes
Generally, Scab can be related to:
A highly contagious disease, also known as chickenpox, is caused by the varicella zoster virus and can be transmitted by contact with infected individuals. Patients should avoid contact with other children or pregnant women.
Mycobacterial infections are multisystem infections caused by the Mycobacteriaceae bacterial family. These infections are complex and more common in people with immune system disorders. They can cause lung infections, leprosy, chronic ulcers, and other localized or widespread infections.
This rare, inherited, lifelong condition causes blistering rashes on the skin, particularly in skin folds like armpits or genitals. It results from a gene defect in cells that help skin cells stick together. Factors that worsen the condition include sunlight, sweat, heat, and friction. It can develop at any age but typically appears in the second or third decade of life.
Related serious diseases
Sometimes, Scab may be related to these serious diseases:
Anthrax is a bacterial infection caused by Bacillus anthracis. Infection can occur from inhaling anthrax while working with infected animals or animal products such as wool, hides, or hair, but it does not spread between humans. Anthrax can cause damage to multiple organ systems, inflammation of the brain and spinal cord coverings, leading to massive bleeding and death.
